Definitions

  • This invention relates to an image formation apparatus capable of designating a recording area, and further to an image formation apparatus having an original reading-out scanner for reading out video signals.
  • a heretofore known method of copying with such a situation has been an optical one which comprises providing a movable mask plate in a portion of the original supporting table of a copying apparatus and masking an unnecessary part of the original by this mask plate.
  • FIG. 1 is a cross-sectional view of an image formation apparatus to which the present invention is applied.
  • FIG. 2 is a perspective view of a tablet.
  • FIG. 3 is a diagram of a control circuit.
  • FIG. 1 illustrates an example of the image formation apparatus to which the present invention is applied.
  • reference numeral 1 designates the body of the image formation apparatus and a tablet input device 2 is disposed on top thereof.
  • the tablet input device 2 as shown in FIG. 2, comprises a tablet 3 and a stylus pen 4, and has the function of converting position designated by the stylus pen 4 into a digital two-dimensional coordinate information data and transferring it to the outside.
  • the tablet 3 is what is called a digitizer, and it is a device which generates pen position information data by the operator operating the pen on an operating board on a flat plate. Such tablet is wellknown and therefore need not be described in detail herein.
  • the upper surface of the tablet 3 is the surface for supporting an original 0 thereon.
  • a laser beam scanning mechanism 10 for scanning a photosensitive drum 9 is disposed below the tablet input device 2.
  • Conventional process means namely, a primary charger 22, a secondary charger 23, a whole surface exposure lamp 24, developing means 25, image transfer means 26, cleaning means 27, etc. are disposed around the photosensitive drum 9.
  • Transfer mediums P to which the image formed on the photosensitive drum 9 is to be transferred are contained in cassettes 28 and 28' and are fed seletively from one of these cassettes by a paper feed roller 29 or 29' and conveying rollers 30 or 30' and conveyed to an image transfer station by further feed means.
  • the transfer medium is separated from the surface of the photosensitive drum by separating means, not shown, and then conveyed to fixing means 31.
  • the transfer medium heat-fixed or pressure-fixed by the fixing means 31 is discharged onto a tray 33 by discharge rollers 32. In this manner, the scanned optical image by the laser beam scanning mechanism 10 is formed on the transfer medium, which is thus used.
  • Read-out means for obtaining video signals for modulating the laser beam scanned by the laser beam scanning mechanism 10 is constructed on a keep surface for holding down the original placed on the aforementioned original supporting surface.
  • Designated by 11 is the housing of the read-out means, and an opening in which a transparent plate 12 is disposed is provided at a location in the underside of the housing 11 which is opposed to the tablet 3 providing the aforementioned original supporting surface.
  • the underside of the transparent plate 12 provides the original keep surface.
  • a scanning unit 13 is disposed so as to be movable on the transparent plate 12 from a position indicated by the solid line to a position indicated by the dotted line.
  • the scanning unit 13 has incorporated therein an illuminating light source 14 for illuminating the original, mirrors 15, 16, 17 and imaging lens 18 fixed on the unit for directing the reflected light from the original to an image sensor 19, and a solid state image sensor 19 such as CCD which is irradiated with the reflected light from the original imaged by the lens 18 (the image sensor comprises, for example, 2048 light-receiving elements arranged linearly).
  • This scanning unit 13 is reciprocally movable along a guide rail (not shown) provided within the housing 11.
  • the upwardly facing surface of the original resting on the original supporting surface is repeatedly scanned by the image sensor disposed perpendicularly to the direction of movement of the scanning unit to thereby obtain a video signal comprising the original information converted into an electrical signal.
  • the video signal may also be obtained from the outside.
  • the thus obtained video signal is utilized to modulate the laser beam from the laser beam scanning mechanism 10 and such modulated beam repetitively scans in a direction perpendicular to the plane of the drawing sheet.
  • image formation is accomplished on the photosensitive drum 9.
  • the read-out by the image sensor and the deflection of the laser beam are in synchronism with each other.
  • the housing 11 is fixed to the apparatus body 1 by means of a hinge H and therefore, to place an original on the tablet 13, the housing 11 may be rotated in the direction of arrow F about the hinge H to bring about an open position as indicated by the dot-and-dash line, and the original may be placed with the housing 11 being in such position.
  • the housing 11 When the coordinates of said part have been input in this manner, the housing 11 is returned to its position indicated by the solid line without the original being moved to thereby bring about a closed position, whereafter the scanning unit 13 may be moved to read out the original.
  • the original may be placed so that the surfae thereof having the information to be copied faces upwardly as viewed in FIG. 1 and therefore, the aforementioned indication by the pen 4 can be effected directly on that surface having the information and the original need not be moved during copying, and this leads to the possibility that editing and copying can be carried out very accurately and quickly.
  • FIG. 3 shows the control circuit of such image formation apparatus.
  • Coordinates T1, T2, T3 and T4 input onto the tablet 3 by the pen 4 are stored at corresponding positions P1, P2, P3 and P4 in a memory 40 having a storage capacity for storing image element information of one page of the original.
  • Designated by 41 is a switch for instructing to record, during copying, the portion surrounded by the coordinates indicated by the pen 4 and erase the other portion
  • denoted by 42 is a switch for instructing to erase, during copying, the portion surrounded by the coordinates indicated by the pen 4 and record the other portion.
  • One of such switches 41 and 42 are selected.
  • a copy start instruction switch 43 is depressed.
  • a write-in instruction is put out from a control circuit 44 to a write-in circuit 45 and, if the switch 41 is in its ON position, a digital "1" is written into the portion surrounded by coordinates P1, P2, P3 and P4 and "0" is written into the other portion, and, if the switch 42 is in its ON position, a digital "0" is written into the portion surrounded by coordinates P1, P2, P3 and P4 and "1” is written into the other portion.
  • a termination signal is sent from the write-in circuit 45 to the control circuit 44, which thus puts out a copy start instruction on a line SL1 and instructs to start movement of the scanning unit 13 and also instructs to start the other operation necessary for copying.
  • the control circuit instructs to start the operation of a read-out circuit 46, which thus instructs the memory 40 and the image sensor 19 to effect readout.
  • a read-out circuit 46 instructs the memory 40 and the image sensor 19 to effect readout.
  • the scanning unit 13 is moved in the direction of arrow F relative to the tablet 3 and that the direction of the scanning of the original by the memory 40 is effected in accordance therewith, that is, movement and read-out in the X-direction takes place while read-out in the Y-direction takes place repetitively, this repetitive read-out in the Y-direction being in synchronism with the repetitive read-out of the image sensor 19 in the R-direction, and the movement in the X-direction being in synchronism with the movement of the scanning unit.
  • the content of the memory 40 and the content of the image sensor 19 thus read out are applied to an AND gate 47, from which the output of the image sensor 19 is put out only when the digital "1" is read out from the memory 40.
  • the coordinates (x system and y system) indicated by the pen may be pre-stored and these coordinates may always be compared with the coordinates being scanned by the image sensor 19 so that the output of the image sensor 19 may be suppressed by the comparison output.
